All dogs are going to -- keep in mind that all dogs are of different temperaments and different sizes and shapes. As I show you the hand strokes that you will use, you can modify those hand strokes and the pressure that you use to match your dog size and sensitivity level. This has been the introduction to how to massage your dog, and in the next sequence we will go over the basics of canine massage.
Some studies have shown that your deep sleep should at least be 20% of your overall sleep. It means that since most adults need 8-9 hours of sleep, they will need about 1.6-1.8 hours of deep sleep to feel fully functional next day.
After stage 3 sleep, stage 2 sleep is repeated before entering REM sleep. Once REM sleep is over, the body usually returns to stage 2 sleep. Sleep cycles through these stages approximately four or five times throughout the night. On average, we enter the REM stage approximately 90 minutes after falling asleep. The first cycle of REM sleep might last only a short amount of time, but each cycle becomes longer. REM sleep can last up to an hour as sleep progresses.
